| Outline of Final Research Achievements |
Some eukaryotes retain non-photosynthetic plastids despite the secondarily loss of photosynthetic ability. In order to unveil the functional transition and evolutionary manner of the non-photosynthetic plastids, comparative genomic survey of genus Cryptomonas (cryptomonads), was carried out using one photosynthetic strain and three non-photosynthetic strains which have lost the photosynthetic abilities in independent occasions. In addition, the whole protein set working in the plastids were predicted based on transcriptome/proteome dataset. My data showed that three non-photosynthetic plastids appear to be reflected each state of the loss of photosynthesis in the convergent evolution despite of they have lost the photosynthesis, independently.
